Seeding Program is about the inception of Pantropy, when the Pantropy program appears to have deteriorated into hideous genetic experimenting and has been outlawed. It describes Sweeney, a modified ("adapted") human whose metabolism is based on liquid ammonia and sulphur bonds and whose bones are made from ice IV, who is inserted into a colony on Ganymede by the Terran Port Authority (a para-military organization) to capture a renegade scientist and end his plans to seed modified humans on distant worlds. However, the government really only tries to derail pantropy because it will cut their profits from terraforming attempts. Sweeney is surprised to find a well established, functioning community on Ganymede and eventually realizes that he was just used as an expendable agent and that he has been fed false hopes about the possibility of being changed into a normal human being who could live on earth. Having found a real home, he switches sides and with his help the Ganymede colony manages to launch their seed ships to secret destinations, beyond the reach of the corrupt government.
